Application filed November 16, 1908. Serial No. 462,776.

Be it known that I, GARNET .W. MoKEE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oar-Window-Clean-' in Devices, of which the following is a clear,

' fu l, and exact description.

thoroughly.

the end portion of a street car havin The object of my invention is to provide a ready and convenient window-cleaner, which is attached to the outside of the car or engine cab and is operated by the motorman or engineer inside the car or cab, by air or steam pressure, without necessitating the opening of the window, and which is ada ted to scrape and clean the window uic ly and This I accom lis by the means ereinafter fully descri ed and as particularly pointed out in the claims.

In the drawings :--Figure 1 is a side view of. the front end of a street car with the end wall in section, showing my improvements applied thereto. Fig. 2 is a front view of a portion of the same drawn to a larger scale.

ig. 3 is a vertical section taken on dotted line 3, 3, Fig. 2. Fi 4 is a section of the full sized two-Way va ve used in connection with my invention. ,Fig. 5 shows a horizontal section of my invention taken on dotted line 5 5 Fig. 2. Fig. 6 is a similar view taken on dotted line 66 Fig. 2. Fi 7 is a vertical section of a fragment of the ront of a car showin a modified form of my invention a plied t ereto.

Re erring to the drawings, A represents its platforms inclosed by a suitable vesti ule', the end walls of which are provided with windows B. I

When it is stormin outside or when it is very cold, objects in ront of the car become very obscure to the motorman because of the rain, snow orfrost collectin on the pane. To avoid thls I have provi ed a W1I1d0W able back a from which a blade I) the length of which corresponds to t adapts scraper comprising a tubular or other suitof the laterally from a head c, on the upper end of projects,

a piston C, whichlatter enters and has re ciprocal play in a c linder D, preferably, arranged and secure .in a vertical position in front of the car below the window. The length of piston C is such'that its throw will correspond to the length of the windowane, and, of necessit the length of the cy inder will be greater t an the piston. I

At a point near the upper end of the cylinder it is provided with a combined inlet and outlet ort d, and at or very near its lower end it re provided with a corresponding port g. These two ports are connected by suitable pipes c and E to a two-way valve F, which latter has one of its four openings connected to an air or steam supply-pipe G and its diametrically opposite opening used as an exhaust port.

The lower head f closin the lower end of cylinder D has trunnions a l therefrom that are journaled in horizonta bearings in the forward ends of arms PTO".

jecting from a late H secured to the front of the car prefera ly just above the lane of the car floor. Near its upper end t e cylinder der is kept bearing against these shou ders projecting later- When the piston is at the lower limitsof its stroke, by a coil construction spring 7c connecting it and said plate J, substantially as shown.

When the scraper is hearing against the lower ed e of the window-pane, the osition of the cy inder will be such that it wi incline from its lowerpivoted end toward the car. As the scraper moves toward the limit of its u ward movement, said cylinder and piston Wlll radually assume a more nearly'perpendicu ar position, and the sprin 7c w1ll stretch and time. keep I the scraperlade pressing against thawindow-pane all the time.

VIQW of this limited movement of the cyliir-t der vthe ortion e and E of the pipes e and E, outsi e of the front of the car, are made flexible by the use of rubber or cloth hose or otherwise.

as to sup ly the air or steam to the lower end.

of the cy mder through pipe E under the piston-head and force the scraper up over the window-pane and at the same time open pipe e'to the exhaust port of the two-way-valve, and then into the top of the cylinder above said piston-head and open pipe E to the exhaust port of said valve, .and vice versa. This operation is repeated as often as desired and until the window is satisfactorily cleaned and then the two-way-valve is turned so as to close both. the inlet and outlet of said valve. 7

In Fig. 7' of the drawings I show a modified construction of my invention, in which the cylinder 2, is secured in an immovable vertical position in front of the car, and the piston 3, thereof, has a vertical -reciprocal movement. A boss, 4, is secured to the upper end of this piston, 3, and a stub, 5, extendsupward and toward the car Window therefrom and has the back 6 of the scraperblade, 7, pivotally secured thereto at about its center of length. The shape of the back of the scraper is such that when moving upward the edge of the blade will alwaysbear against the glass,-the resistance opposed to said edge preventing the scraper from moving on its pivot. When the scraper moves downward, however, the pressure of the scraper-blade will be less than when moving upward, and when it is very near the limit of its downward movement, the back thereof will strike a spur, 9, secured to and arising from a screw-plate attached to the outer window-sill, at about midwav the length of same and cause the scraperlade to swing around on its pivot away from the window. When, however, the scraper is caused to move upward, the back of the scraper-blade, which isthen nearest the spur, will be engaged thereby and caused to swing around so that the blade comes again in contact with the window.
